What Does Pass Mean In Fire Safety
How To Use a Fire Extinguisher

    • How To Use a Fire Extinguisher
    • It’s easy to remember how to use a fire extinguisher if you can remember the acronym PASS, which stands for Pull, Aim, Squeeze, and Sweep.
    • Pull the pin.
    • This will allow you to discharge the extinguisher.

    Aim at the base of the fire. If you aim at the flames (which is frequently the temptation), the extinguishing agent will fly right through and do no good. You want to hit the fuel. Squeeze the top handle or lever. This depresses a button that releases the pressurized extinguishing agent in the extinguisher. Sweep from side to side until the fire is completely out. Start using the extinguisher from a safe distance away, then move forward. Once the fire is out, keep an eye on the area in case it re-ignites.

The six main fire extinguisher types are water, foam, CO2, powder, water mist and wet chemical. Each of the different types of fire extinguisher is suitable for different fire classes, It is important that you purchase the right fire extinguisher for your needs. * We do not recommend using water mist on anything above a 5F rated fire (this is equivalent to an average domestic deep fat fryer).

The Fire Triangle

Take a look at the following diagram, called the ” Fire Triangle ” Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.

What are the 4 stages of fire?

what are the basics of fire dynamics

03 December, 2021

The first step in fighting fire is to understand exactly what a fire is. Simply put, a fire is a rapid chemical reaction, oxidation to be specific, that produces heat, light, and smoke as part of combustion. The processes that start a fire can be graphically explained through the fire tetrahedron, which shows that for a fire to start, it needs four items: fuel, heat (energy), an oxidizer, and an uninterrupted chemical reaction. 1. The Four Stages of Fire Development There are four stages of fire development: ignition, growth, fully developed, and decay. The ignition stage is when all four elements of the fire tetrahedron coalesce, the fuels reach their ignition temperature, and the fire begins.

  1. During the growth stage, the fire increases fuel consumption and creates more heat and smoke.
  2. The fully developed stage occurs when the maximum amount of fuel and oxidizers are consumed, and the highest heat release rate is produced.
  3. The temperature decreases and intensity is reduced during the decay stage, which happens when the available fuel has been consumed.2.

Determining a Fire’s Intensity Generally, the intensity of a fire is defined by its heat release rate, measured in kilowatts or BTU/second, and the higher the heat release rate, the more intense the fire is. Heat release rate can be modeled as a power law growth model, the most common of which is known as the t 2 -model (t-squared).

Within the t 2 -model, fire growth is classified as slow, medium, fast, or ultrafast, where the heat release rate is dependent on the time of the fire. Choosing the correct fire intensity is paramount when designing a fire protection system. For instance, a slow growth fire might be appropriate for an office building with a limited fuel load and the fire suppression system would be relatively light and simple.

However, a tire storage warehouse might have an ultrafast fire and the suppression system would need to be designed accordingly. Modeling a slow growth fire in that tire warehouse would be a poor basis of design.3. Heat Transference A major aspect of fire dynamics is to understand how heat is transferred to and from a fire.

  1. There are three main methods of heat transfer: conduction, convection, and radiation.
  2. Conduction is when heat travels through a medium via direct contact and transfers energy from a higher state to a lower state.
  3. Another way to understand conduction is the way that if a metal spoon is heated on one end, the heat will move to the other end of the spoon, burning the hand that is holding it.

Convection occurs when heat energy is transferred via air. An example of convection is when a cake is being baked in the oven; the energy from the heating elements is transferred to the flour through the air. Radiative energy does not need a medium (air or direct contact) to transfer energy.

Radiation involves electromagnetic waves that excite target molecules, such as microwave energy. Many of the fire codes are based on studies of fire dynamics. For instance, the separation of buildings is driven by the heat release rate and radiative energy that would be produced by a theoretical fire.

If buildings are too close to each other and one catches fire, there is a good chance the fire will spread to other buildings. The study of fire dynamics has immediate real-world applications to how the built environment is constructed. Interested in learning more about fire protection engineering?

What are the 4 elements of fire?

The Fire Tetrahedron (A pyramid) – For many years the concept of fire was symbolised by the Triangle of Combustion and represented, fuel, heat, and oxygen. Further fire research determined that a fourth element, a chemical chain reaction, was a necessary component of fire.

The fire triangle was changed to a fire tetrahedron to reflect this fourth element. A tetrahedron can be described as a pyramid which is a solid having four plane faces. Essentially all four elements must be present for fire to occur, fuel, heat, oxygen, and a chemical chain reaction. Removal of any one of these essential elements will result in the fire being extinguished.

The four elements are oxygen to sustain combustion, sufficient heat to raise the material to its ignition temperature, fuel or combustible material and subsequently an exothermic chemical chain reaction in the material. Each of the four sides of the fire tetrahedron symbolise the Fuel, Heat, Oxygen and Chemical Chain Reaction.

Theoretically, fire extinguishers put out fire by taking away one or more elements of the fire tetrahedron. This model, although simplistic, is a good analogy as to the theory of how to extinguish a fire. For example, a foam extinguisher would create a barrier around the combustible materials and cut off the supply of oxygen as well as reducing heat.

By applying water you can lower the temperature below the ignition point, or for a flammable liquid fire it would remove or divert the fuel. Finally, interfering with the chemical chain reaction is possible by “mopping up” the free radicals in the chemical reaction using BCF and other halon extinguishers, which also create an inert gas barrier.

Why are passes important?

Importance of Passes –

People regularly use passes to get across mountainous mountain ranges since it is the most convenient option. As a result, throughout history, they have played a key role in human movement, trade, and settlement. Passes are ideal locations for villages or defensive outposts since they are often the only level territory in a mountainous area. From this vantage point, a pass is also easier to defend against threats or foes. Passes act as a link between cultures that are separated by mountains in several places of the world. The Khyber Pass, which goes over the Hindu Kush mountains and connects Pakistan and Afghanistan, has been an important trading route between Central and South Asia for thousands of years. It now connects Afghanistan’s and Pakistan’s modern cities of Kabul and Peshawar.

Intransitive sense of “to go on, to move forward, make one’s way” is attested from c.1300. The figurative sense of “to experience, undergo” (as in pass the time ) is recorded from late 14c. Sense of “to go through an examination successfully” is from early 15c. Meaning “decline to do something” is attested from 1869, originally in cards (euchre).

In football, hockey, soccer, etc., the meaning “to transfer the ball or puck to another player” is from c.1865. Related: Passed ; passing, The meaning “to be thought to be something one is not” (especially in a racial sense) is from 1935, from pass oneself off (as), which is attested by 1809.

  • The general verb sense of “to be accepted as equivalent” is from 1590s.
  • Pass up “decline, refuse” is attested from 1896.
  • Pass the buck is from 1865, said to be poker slang reference to the buck horn-handled knife that was passed around to signify whose turn it was to deal.

These devices are most commonly worn by firefighters or other individuals who work in immediately dangerous to life and health (IDLH) scenarios.

What are the 4 types of fire extinguishers?
